Compaction in Granular Solid Hydrodynamics
Yimin Jiang, Mario Liu
TL;DR
This paper integrates compaction phenomena into granular solid hydrodynamics, linking reversible compaction to pressure in dense flow and irreversible compaction to elastic deformation loss, enhancing understanding of granular behavior.
Contribution
It introduces a unified framework for modeling both reversible and irreversible compaction within granular hydrodynamics, connecting physical mechanisms to granular flow behavior.
Findings
Reversible compaction correlates with pressure in agitated grains.
Irreversible compaction arises from elastic deformation loss.
The model explains elasto-plastic flow dynamics.
Abstract
Compaction is considered and embedded into broader granular behavior. Reversible compaction is related to the pressure exerted by agitated grains, a quantity relevant to dense flow. Irreversible compaction is derived from the loss of elastic deformation, the physics behind elasto-plastic flows.
